Why is corn used to produce ethanol when there are several other better and more energy conscious choices? ie biomass, sugar cane, switchgrass.

Some studies show that ethanol production via corn uses almost as much energy as it makes.
Future Sources of Ethanol

Fermenting the corn takes more effort than other crops (sugarcane). Corn uses higher quality soil to grown than other crops (switchgrass). Corn competes directly as a food source.

Don't worry, we will be importing ethanol and sugar. There is no way we can become energy independent making ethanol from corn.
Just another cockamamie scheme like the solar industry wasting taxpayer money.

Switchgrass grows in all types of soils, cheaply and easily. I believe corn is used for political reasons.

This is a moot issue and here is why.

You cannot grow sugarcane except in a few states. Basically we are talking Texas, Florida, and Louisiana.

sugarcane takes much longer to grow than corn and other grain crops. Also once sugarcane is harvested it much be used right away while the sugar content is high. With corn and other grains it can be harvested and stored for months.

Switchgrass and other bio crops are still under development. So far no one has been able to produce them economically in sufficient quantity.

giwan, if biomass and switchgrass(a form of biomass) is so much better than corn, why haven't they found a way to economically produce ethanol with them? How much sugar cane do you think they can grow in the US?

I don't care how they make ethanol. I'll keep buying it as long as it costs less than gas.

Nice site giwan. Regardless of source, ethanol is a great fuel for this country to have available to consumers. It doesn't have to be from corn.

Has anyone ever asked THIS question? As all these technologies for non food based ethanol and biofuels were emerging, all of a sudden energy prices spike, causing a massive global recession! This petroleum-caused recession derails many investments in liquid biofuels that are superior to that same petroluem, just as they had the potential to be market ready? Since petroleum had a monopoly at the time, ever think that that was no coincidence?

hmmmmm.....

Someone needs to answer these questions.
Also, if the move to E85 from E10 takes place, it is obvious that we will need more than 8 times as much ethanol.What is the plan to produce all that ethanol?
The ratio would be more actually because the gas mileage will drop significantly.
I think the corn growers are leading us down a blind alley.
